I just setup my two servers, one had a 30 gig web data dir and the other an empty dir. I ran this command on the 30 gigs and then mounted on a client machine and watched it happily delete my entire web data. I am now at work after a mad rush here to launch our backup software and restore from last night. Oh the joys of sysadmining... sucks when it is your own damn fault. I had to tell my boss, oh sorry, your message boards and orders for today are lost. Oops! So once I do a little more testing with this I will try to throw some documentation together myself so other people dont find themselves in this situation. Thank goodness for backups!
